Because of the concern remained about the credibility of embankment and retaining wall built along the housing development, the foundation was laid on natural ground beneath the lower tier which was more reliable as the supporting stratum.

由于对周边开发建筑的堤防和挡土墙信誉度的关注，后建筑的地基就建在了天然地面上，作为支撑层更加可靠。

The headmen also supervised community projects such as dike repairs, crop watching, or militia operations.

The project has produced an easy to carry guide which illustrates the various routes on offer, including eight tunnels, eleven bridges, six viaducts, and many passages and embankments.

这个专案出版了便於携带的指南，描绘出不同需求的路线，包括8条隧道、11座桥、6座高架桥，还有很多通道和堤防。

This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.

本文介绍了平面二维水流二维模型研究进展，对河道历史演变概述，通过最新原型观测资料对河道近期主泓线、断面、洲滩、河床冲淤、码头附近冲刷坑等进行详细分析，总结近期河道演变规律，并参考有关文献，对三峡建成后河道演变趋势进行预测；建立了平面二维水流模型，并根据最新资料对模型进行率定和验证，采用模型对几种工况组合进行壅水和流速计算；采用国际上广泛应用的Geo-Slope滑坡稳定分析程序对几种工况条件下工程断典型断面岸坡进行稳定性计算；最后总结工程建设对洪水位、流速、河势、堤防及防洪抢险等方面进行综合评价，得出码头建设对行洪影响较小的结论。

Passepartout was furious at the delay they occasioned, and longed to discharge his arsenal of revolvers upon them.

它们简直是活肉形成的河流，任何堤防也挡不住。旅客们都跑到车桥上看这个奇怪的场面去了。
